Fire Hydrant Flow Testing

About this project

We are undertaking routine water flow and pressure testing of approximately 4,500 fire hydrants across the City as part of a proactive maintenance program.

To maintain fire hydrants for use by Queensland Fire and Emergency services, we test fire hydrants to gauge flow and pressure and make sure they are fully functioning in case of an emergency.  While we already maintain fire hydrants, further testing will help determine the performance and condition of hydrants and allow us to identify those which need future maintenance or replacement.

Testing of fire hydrants will occur on week days between 7:00am and 5:00pm.  The works will commence from early August 2019 and continue through to November 2019.

There will be no interruption to residents’ water supply during the flow testing of fire hydrants.

Some water will be released into the stormwater network as each hydrant tested. Keeping this water is not cost effective when compared to the cost of hiring a truck to capture any lost water. However, Council officers and contractors will endeavour to minimise water wastage, where practical.

Logan South Wastewater Treatment Plant B

In 2018/2019 Council has been looking into potential sites for a modern wastewater (sewage) treatment facility in the City of Logan. This facility, currently known as Logan South Wastewater Treatment Plant B (Logan South WWTP B) is needed to service new developments between Park Ridge and Yarrabilba in the coming years.

Current status

At the Ordinary Council meeting of 16 April 2019, Council selected a final site for the Logan South WWTP B. The site is located at the eastern end of Pleasant View Road at Chambers Flat.

The selected site was considered the most suitable for a modern wastewater treatment facility due to the availability of flood free land, the relatively low impact on the community and environment compared with other sites assessed and the proximity to the Logan River.

The project is currently is in the early planning phase. Council is commencing detailed planning and concept design of the facility.

Community consultation

Chambers Flat community members may register their interest in participating in a Community Reference Group which will inform the future development of the Logan South WWTP B. Please contact Tania Keelan on 3412 9609 or email
